Use MQCMD_INQUIRE_Q instead of queue.inquire

[AlexandreYang]

What does this PR do?

Since we added support for local queues, when a local queue is assigned to a cluster, the method queue.inquire will raise this warning: WARNING: MQRC_SELECTOR_NOT_FOR_TYPE

But using MQCMD_INQUIRE_Q does not have this issue. That will also avoid calling the IBM MQ server only once instead of once per attribute we want to get.

Motivation

I don't understand what you mean there

This change is also included in #3977

Careful when merging/rebasing the other PR #3977.

Previously, we call queue.inquire(pymqi_value) for each attribute of a specific queue (x30 queue metrics)

Now, calling pcf.MQCMD_INQUIRE_Q(args) retrieve all attributes of the queue at once. Then we process those queue attributes to submit the metrics.
